John - periodic upgrades get made to the programming that makes ChoralNet work by ChoralNet's Manager and Webmaster. They are tested in a separate, non-public version of ChoralNet and then applied, usually without any particular fanfare or announcement (except for really major changes). The most recent update had several bugs in it, including the one that broke the URLs in the ChoralNet Daily and Subscriptions messages. I immediately reported the problem and they rushed out a fix (as Allen mentioned).

There are a couple of bugs remaining today, but Allen and Martin are working on fixing them. They include problems with the user-customization of the placement of items on the Home page and on Community pages.
